Chapter 36 (2/2)
Donate some money anyway.
After all the awards are awarded, the winners will take a group photo on the stage, and then there will be various artistic performances and donation activities.
Zhang Yuan stepped down and sat quietly in his seat.
Professor Wang patted him gently and gave him an encouraging look.
”Professor Wang, am I right?”
”That's very good!” Wang Zhong said with a smile.
Professor Wang Zhong looked at the capitalists who came to the stage to donate money. He secretly sighed: ”if Mr. Qi Yuanshan can see this scene, he will be very happy.”
Everything in the world is for profit. Even if these capitalists only want to earn money, they are not ”ideal”, it is also a good virtuous circle.
It's easy to add flowers to the icing on the cake, and it's difficult to send charcoal in the snow. The difficult days were a story a hundred years ago. Even Wang Zhong hasn't been born.
Qi Yuanshan, known as ”Einstein in material science”, is a real giant in material science.
The three most outstanding achievements in his life are ”high magnetic saturation superconducting materials” and ”mass manufacturing of carbon nanotubes”; Third, of course, some sociological contents of the new civilization school.
Why is controlled nuclear fusion difficult? There are many reasons, such as neutron radiation, triple product, and a very important point is that the magnetic field constraint is not strong enough.
The magnetic field constraint must be strong enough to bind the violent plasma and make the fusion reaction in the circulator stable and last longer.
But if you want to have a large enough magnetic field, you don't just increase the current.
There is a phenomenon of ”magnetic saturation” in materials science. When the applied current and coil density reach a certain size, the magnetic field will not increase further.
Anyway, no matter what happens, there is only such a point in the magnetic field. The rest depends on yourself.
When the magnetic field constraint reaches the limit, it is still not strong enough to bind the plasma, which has become a problem with almost no solution.
Professor Qi Yuanshan's breakthrough ”high magnetic saturation superconducting material” simply and rudely increased the original magnetic field strength by a full 10 times!
10 times!
As a result, the violent plasma was bound obediently, and many problems were no longer problems. ”Controllable nuclear fusion technology” came late and finally appeared in the world.
In that era of no oil and lack of energy, Professor Qi's reputation was naturally at its zenith, known as the ”father of nuclear fusion”.
The second major achievement is the mature production technology of carbon nanotubes, which makes carbon nanotubes very cheap. The tensile strength of this material is more than 100 times that of steel, and the density is only 0.03 grams per cubic centimeter. It is a very excellent building material.
Such a scientific giant, whose influence has been extended to modern times, is an admirer of many scientists.
However, at that time, Professor Qi's ”construction plan for space elevator” was rejected by the government.
Because the investment is so large that Xia Guo, who has just recovered from the energy crisis, is difficult to accept
……
As for what happened later, so that the government's attitude has changed greatly, Wang Zhong doesn't know.
All he knew was that the space elevator was built as scheduled and was almost completed when he was born.
After gambling on the national luck for 20 years, Xia finally gambled on a bright future!
This part of the past, even now, is often talked about by historians.
A country's development, step by step first, step by step first.
So is a civilization.
Without that brave step, the earth still does not have a space elevator, and there will be no beautiful present.
